Though known members of the archconservative group represent only 9 percent of House Republicans, Freedom Caucus members make up nearly a quarter of the scheduled contacts of their former founding member, Mick Mulvaney, in his first six months as Office of Management and Budget director.

Despite the fact that no House Freedom Caucus members are in positions of committee or party leadership, they've got Mulvaney’s ear.

Mulvaney scheduled talks with nine individual members of the caucus 15 times, nearly as often as he did with House Republican committee leaders (17), according to a copy of his schedule acquired by transparency group “Property of the People.” GOP leaders had contact only seven times.
